Reheating microstructure of refined AZ91D magnesium alloy in semi-solid state JIANG Ju-fu(姜巨福), LUO Shou-jing(罗守靖) (School of Materials Science and Engineering, Harbin Institute of Technology.... With increasing equivalent strain, the average grain size decreases. This demonstrates that reheating material extruded by ECAE technology is a good method to prepare AZ91D magnesium alloy semi-solid billets. Key......
solid solution at random. The region at darker color located at the grain boundaries was the eutectic phase which consisted of α-Mg and Mg17Al12 (β phase). Fig.2 Microstructure of magnesium alloy chip... AZ91D magnesium alloy was explored. Generally, the matrix consisted of α-Mg eutectic solid solution and inter-metallic β phase surrounding the grain boundary, and the solid phase particles......

Feasibility of Substituting Cerium-Rich Metal by La-Pr-Ce Alloy in Magnesium Alloy 赵平1,伏思静1 (1.Department of Material Science & Engineering,Xihua University,Chengdu 610039,China) Abstract:In magnesium alloy ZM3, using cheap Lanthanum-praseodymium-cerium (LPC) rare earth as a substitute for rich-cerium rare earth was studied. The experimental results show that when the adding amount of LPC......
the electrochemical anode and cathode polarization behavior of the alloy. Key words: magnesium alloy; corrosion; electrochemical properties; indium 1 Introduction Mg alloys have many advantages...; (1) the amount of Mg corroded of a magnesium alloy corresponds to the volume of evolved hydrogen. Therefore, the hydrogen evolution method is more reliable in studying......
